Falco Spara, Pactweaver + Sensei's Divining Top + Kykar, Wind's Fury + Toothy, Imaginary Friend

Falco Spara, Pactweaver

Sensei's Divining Top

Kykar, Wind's Fury

Toothy, Imaginary Friend

How it works

1. Activate Sensei's Divining Top's second ability by tapping it, causing you to draw a card and put Sensei's Divining Top on top of your library.
2. Toothy triggers, putting a +1/+1 counter on it.
3. Cast Sensei's Divining Top from the top of your library by paying 1 and removing a counter from a creature you control.
4. Kykar triggers, creating a 1/1 Spirit creature token.
5. Activate Kykar by sacrificing the Spirit, adding .
6. Repeat.

This clever loop turns the top of your library into an endless engine, fueled by the unique casting permissions granted by Falco Spara, Pactweaver. By tapping Sensei's Divining Top to draw a card and place itself back on library, you trigger Toothy, Imaginary Friend to grow with a new +1/+1 counter—which Falco Spara can then immediately consume as payment to cast Sensei's Divining Top right back off the library. Meanwhile, Kykar, Wind's Fury watches every noncreature spell you cast to effortlessly spawn a 1/1 Spirit token, which can be sacrificed right away for red mana to keep the {1} casting cost continuously paid.
